I have had my Sony KDF-42WE655 for about 11 months now. 2 nights ago I noticed the picture kind of blinking between the setting of standard picture and vivd, what I normally have it set at, a few times. I thought it was my eyes, actually. Last night it did it again,....alot. It gets bright, then dimmer,...........brighter....dimmer. Sometimes it does it very quickly, other times it will stay at one or the other for several seconds. I called Sony, and they gave me a few local phone numbers to call to have someone come out to look at it, under warrentee. Before I do that, has anyone else have a similar experience? If so what did it turn out to be? Also I forgot to mention it does it on all inputs, I have an HP Z555 entertainment PC w/directv pumping through it as my maine input, but also have an x-box 360 it does it with, and the OTA HD tuner in the tv itself it does it with, also. Is it bulb getting ready to let go?
